• Water resistance

As the water resistance will be reduced over time, you should have your watch inspected and

its water resistance verified every 2-3 years (charge basis) to extend its life and ensure safety. To

maintain its water resistance, it is recommended to request us to replace the packings and other

parts of your watch.

• Disassembling for internal cleaning (repair)

You should have your watch disassembled and its internal components cleaned periodically

to extend its life. Lubrication oils are used to reduce wearing of moving parts such as gears.

However, over time the lubrication oils will degrade and wear will increase, eventually resulting

in malfunction. Please have your watch undergo internal cleaning every 5 years (although the

maintenance frequency depends on the usage circumstances).

All parts of this watch, except for the band, are to be repaired only at CITIZEN. This is

because special technologies and equipment are required to perform repairs, inspections and

adjustments. Please make requests for repairs to an authorized service center when having your

watch repaired.

If you have any questions regarding the way warranty, repairs or other matters, please inquire at

the shop where you purchased your watch or an authorized service center.
